State Fossil: Teredo Petrified Wood (1967)
North Dakota doesn’t have a wide variety of rocks and minerals, but what it does have are high quality and are fairly abundant.
The best places to rockhound in North Dakota are along major rivers and their tributaries, particularly the Yellowstone, Missouri, and Cannonball Rivers. Quartz-family gemstones like agate, chalcedony, and jasper are commonly found in their bars, banks, and gravels.
Please note that rock collecting locations are always changing so be sure to check with the site owner for the most current information before going.
Dig safe, never go underground, and make sure to get permission from the landowner to search for and collect rocks.
